I can find the female on male murder rate for most countries quite easily, and if it's not recorded, the number of women arrested for murder.
No such data is available for Ukraine - is that really the case? Or is it being hidden to keep people from rejecting the "refugees"?
Has it occurred to you that if Ukrainian women were so eager to slake their bloodlust by killing men, they would have just stayed home? Why would the Ukrainian government send its women away right when they had a whole lot of Russian men who needed killing?
Same reason why women in the US scream about killing all men but recoil at the idea of being drafted.
They don't like their targets to know they're being targeted.
Edit : Definitely hit a nerve here.
